摘要： A non-resonant electromagnetic energy sensor which generates output signals upon the quantitative and/or qualitative detection of the flow of various substances including solid particles flowing as discrete individual particles or as a continuum, as well as the flow of liquids and/or gaseous substances. The non-resonant electromagnetic energy sensor may be interfaced with various types of electronic circuitry whereby the generated output signals may be used for monitoring a variety of flowing substances, for example, seed flow in an agricultural planter, crop yield on a combine harvester, and flow rates of liquids or gaseous fluids through conduits. The sensor comprises a housing having wall members defining a chamber having an interior volume. The sensor is designed to be interposed along a length of conduit through which the material or substance to be analyzed will pass. An electromagnetic energy source and an electromagnetic energy detector are in communication with the interior volume of the chamber. The electromagnetic energy source propagates non-resonant electromagnetic energy of a predetermined frequency and amplitude into a measuring region within the interior volume of the chamber. The electromagnetic energy detector detects the signal variations of the electromagnetic energy within the measuring region caused by the perturbation of the electromagnetic energy field due to the passage of the analyte therethrough and responds to these signal variations by generating output signals. These output signals may then be received by electronic circuitry designed for particular monitoring needs interfaced therewith.

摘要： A dual-mode optical device selectively operative in signal generation and amplification modes is disclosed herein. The dual-mode device includes a body of semiconductor material having opposed from and rear facets. During operation in the amplification mode, light is input through the front facet and is amplified within the body of the optical gain material. An at least partially optically reflective surface is positioned a first predetermined distance from one of the facets during operation of the device in the amplification mode. In the signal generation mode, the at least partially optically reflective surface is positioned a second predetermined distance from the one facet so as to induce optical oscillation within the body of semiconductor material. In a preferred implementation, a semiconductor diode laser having opposed first and second facets is utilized as an optical source. An at least partially optically reflective surface is positioned a predetermined distance from one of the first and second facets in order that a resonant cavity is formed therebetween. The predetermined distance between the at least partially optically reflective surface and the one facet may be modulated, thereby allowing modulation of optical output produced by the semiconductor diode laser.

摘要： A thin film resonator (TFR) antenna is disclosed which is characterized by substantially lower effective dielectric constant for the layer of dielectric material deposited between the ground metal layer and the top metal layer (transducer) of the TFR antenna. The dielectric constant is substantially lowered by forming an array of dielectric posts in the dielectric layer. The posts support the top metal layer of the TFR antenna. The interstices between the posts are occupied by air in the preferred embodiment. The lower effective dielectric value results in reduced ohmic losses which in turn leads to enhanced gain in the TFR antenna system.

摘要： An acoustically coupled antenna which can be configured as a transmitting or receiving antenna for coupling between an electrical circuit (transmitter or receiver) and an electromagnetic propagating medium such as the atmosphere. The antenna is a two port device in which one port is connected to the electrical circuit and the second port includes a transducer which interfaces (radiates or receives) electromagnetic energy with the propagating medium. The ports are acoustically coupled to each other by forming the device as a stacked crystal filter with three conductive electrodes separated by two piezoelectric resonating elements. The first port comprises two of the electrodes separated by one of the piezoelectric elements, and the second port shares the electrode separating the two piezoelectric elements, and further includes the second piezoelectric element and the final electrode. The electrical signals in the bandwidth of the antenna at the two ports are acoustically coupled by the coupled resonators of the stacked crystal filter for translating energy from one port to the other while providing electromagnetic isolation by virtue of the acoustic coupling.

摘要： A pre-pulsed magnetic field generation circuit for a fiber-based, magneto-optic (MO) optical modulator or switch for use in an interferometer is provided. The pre-pulsed magnetic field is used to control the amount of rotation in the state of polarization (SOP), and therefore, the ON-OFF extinction ratio. The circuit includes a pair of amplifier circuits that control the current through a coil to generate the pre-pulsed magnetic field. One amplifier controls a magnitude of a steady state portion of the magnetic field, while the other controls both the amplitude and duration of a pre-pulse portion of the magnetic field.

摘要： An integrated fiber optic switch based on the magneto-optic effect of magnetic materials suitable for optical fiber networks is presented. The switch is based on the Faraday Effect exhibited by magneto-optic materials. The all-fiber magneto-optic switch has a beam splitter at the input that splits an incoming signal into orthogonal polarized paths. Each path has at least one magneto-optic Faraday rotator (MOFR) controlled by a field. When the field is present, the polarization of the optical beam changes, thereby turning the switch on or off. A beam coupler couples the orthogonal polarized paths at the output of the all-fiber magneto-optic switch. The switch is constructed in the Mach-Zehnder configuration, utilizing two 3 dB couplers, isolators and MOFRs fabricated on silicon-on-insulator.
